The Clippers

After the Donald Sterling scandal in May 2014, Ballmer was the highest bidder for the Los Angeles Clippers, at a reported $2 billion. He has since financed the Intuit Dome arena. In September 2025 the journalist Pablo Torre reported that Ballmer and the Clippers used the company Aspiration to pay Kawhi Leonard an extra $28 million, circumventing the NBA salary cap. Ballmer and the Clippers say they were the victims of a fraud by Aspiration.

Philanthropy

Ballmer is a co-founder of the Ballmer Group, a philanthropic investment company.

Why It Matters

Ballmer remains one of Microsoft’s largest individual shareholders, so his wealth rises with its share price, and his team ownership keeps him in the public eye.
